Embodiment

[0023] Such as figure 1 As shown, the oxygen system of the A320 aircraft crew provides oxygen through oxygen cylinders, and the oxygen cylinders are distributed and transmitted to multiple oxygen masks through the delivery pipeline for use by the captain and passengers. The oxygen cylinder is connected with a pressure regulating assembly and a solenoid valve for cutting off the oxygen supply. The solenoid valve is connected to an oxygen-operated supply control switch. The ECAM OXY / DOOR page displays the oxygen pressure value. The invention provides a monitoring method for the oxygen system of the A320 aircraft crew.

[0024] The invention relates to a method for monitoring oxygen leakage of an A320 unit, comprising the following steps:

[0025] Step 1. Preset the oxygen normal consumption threshold of the oxygen system of the A320 unit.

[0026] Step 2: ACMS Aircraft Condition Monitoring System (Aircraft Condition Monitoring System) and Quick Access Recorder (Quick access ...

Abstract

The invention relates to an A320 unit oxygen leakage monitoring method. The method comprises the following steps of (1) presetting an oxygen normal loss threshold of an A320 unit oxygen system, (2) allowing an ACMS and a QAR to record oxygen pressure data of ECAM OX / DOOR in a flight process, (3) allowing the ACMS data and the QAR to transmit the oxygen pressure data of ECAM OX / DOOR to a ground workstation through an air-ground network and in a wireless mode, and (4) the ground workstation carries out analysis processing such as decoding on all the obtained data and judges whether oxygen leaksor not according to the actually obtained oxygen pressure data and a set oxygen normal loss threshold value to achieve the monitoring of the A320 unit oxygen system. Compared with the prior art, the method has the advantages of reducing the operation risk and improving the working efficiency.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to a method for monitoring oxygen leakage of an A320 unit. Background technique [0002] The aircraft crew oxygen system is designed to provide oxygen to the crew during emergency decompression of the cabin or when smoke, toxic gases, etc. appear in the cockpit. Leaks in the oxygen system of most aircraft crews will not trigger cockpit warnings, and the crews often do not specifically monitor the oxygen pressure continuously during the flight. When a leak occurs, it is not easy to detect. Oxygen, on the other hand, is flammable and explosive, and leakage also poses risks in use and maintenance. [0003] For most A320 aircraft, when the pressure is lower than 1500PSI, an amber semi-frame indicator will appear on the oxygen pressure indicator on the ECAM OXY / DOOR page, reminding maintenance personnel to perform oxygen cylinder duties to avoid abnormal leakage and excessive oxygen c...
